Vol. 1 - Theory. A theory for simulation and optimization of an irrigation system to evaluate improvement alternatives was presented. The mathematical simulation model of an irrigation system was developed combining existing models of conveyance, application and water use subsystems. The performance of the subsystem simulation models was verified using available field data from Pakistan. A methodology for the optimal design of a level basin irrigation system was described. Irrigation system improvement alternatives such as canal lining, earthen improvement of the application system were evaluated. Vol. 2 - Application. Wheat production on a watercourse in Pakistan was analyzed. Models for water conveyance, application, and water use subsystems were calibrated with data from the study area. The existing irrigation system operated at a 39 percent application efficiency and 53 percent conveyance efficiency. Optimal design of the application system with precision land leveling provided net benefits of 3625 rupees (Rs) compared to Rs 2612 under traditional field conditions. Canal lining was not economical. Earthen improvement of the conveyance system was beneficial to the farmer with a net profit of Rs 3304. Combined improvement of the application and conveyance systems almost doubled the total net benefits over the traditional system, but with an increased level of investment. The increase in benefits was mostly a result of the increased irrigated area that could be irrigated after the improvements. The benefit/cost ratio of each improvement alternative was different. The difference in benefits between improving the conveyance system and the application system was small, but there was a significant difference in net benefits between any single improvement and the combined improvement of the application and conveyance systems.

The book reviews alternative approaches to pre-sanction appraisal of irrigation projects such as those suggested by the Second Irrigation Commission, the World Bank and UNIDO. Details of alternative methodologies and social benefit cost analysis (SBCA) of various technical alternatives have been presented by using the Auranga Reservoir Project in Bihar as an illustration. A computer programme in Fortran 1V has been included as a useful tool for performing necessary appraisals and sensitivity analysis.

Over half of the water supplied to the watercourse at Tubewell 56L was lost before it reached the farmer's fields. This loss was primarily through the upper porous portions of the banks and in the vicinity of junctions where banks were thin. The 35 farmers in the 900-acre area served by this watercourse were motivated to organize themselves to rebuild their own earthen watercourse, according to specifications drawn up by Pakistani engineers. Low cost concrete diversion structures were developed and installed at junctions to eliminate continued burrowing of soil and degradation of banks near the junctions. The improvements reduced losses to about one-half their previous values and increased deliveries to the fields by over 50 percent. This watercourse improvement appears to be an ideal component for a development program designed to increase crop production. However, farmers require further information on how to use this water and other inputs to optimize crop production if they are to obtain full benefits from this extra water.

(Location: IWMI-HQ Call no: P 1076 Record No: H0710)
Estimates of net private and social benefits to irrigation water supply are shown for a case study area in the northern Nile delta region of Egypt. Net benefits are defined as gross revenues minus costs of production, including an imputed charge for family labor. Linear programming models of representative farms in the study area are formulated with particular reference to the possibilities of using less water per crop or shifting crops in response to changes in water supply. Model solutions are based both on government prices (with production controls) and hypothetical international market prices (with relaxed controls). Five different water supply scenarios are analyzed from current adequate levels of supply down to 40 percent reduction from that level. Total, average, and marginal net benefit functions are reported. Implications of the differences between the social and private benefit functions are discussed.
